Abstract: A multi-band antenna includes a first radiator resonating at a high frequency bans and a second radiator extended from a first end and toward a second end of the first radiator, and resonating at a low frequency range. An opening slot is formed between the first and the second radiators. A connecting slot and an end slot are formed in the second radiator. The width of the connecting slot is wider than the width of the opening slot. The connecting slot can prevent vectors potential caused by the second radiator from being neutralized. The electromagnetic coupling effect over the opening slot caused by the first radiator and the second radiator can pull down the low frequency range for reducing the size of the second radiator. Therefore, the multi-band antenna has a small size.
